Which statement correctly describes both CD4 and CD8 proteins?
A) secreted by antigen-presenting cells
B) receptors present on the surface of natural killer cells
C) molecules present on the surface of T cells that interact with major histocompatibility (MHC) molecules
D) molecules on the surface of antigen-presenting cells where they enhance B cell activity

Question

Quizplus · Accepted Answer

CD4 and CD8 are co-receptor molecules present on the surface of T cells. CD4 molecules are typically found on helper T cells and interact with MHC class II molecules, while CD8 molecules are found on cytotoxic T cells and interact with MHC class I molecules. Both are crucial for the T cell's ability to recognize and respond to antigens presented by MHC molecules on antigen-presenting cells.
